ROTARY GAN WASHER.

Application ledebruary 27, 1925. Serial No. 11,916.

The invention will be best understood byv reference to the accompanyingdra-wingsforming a part of this specification, and in which, .I Fig. 1represents a side elevational view of a machine constructed inaccordance with the present invention;

Fig. 2 is a central vertical section taken approximately on line 2 2 ofFig. 3;

Fig-3 is affcross section through the machine taken approximately online 3-3 of Fig. 2; and l Fig. Li-'is a fragmentary-plan and sectionshowing the plate means for .protecting the compartment with which thedoorway is reg'A istered.

In the drawings, wherein I have illustrated the preferred embodimentof,my 1nvention, the reference character 4 denotes a circular series ofleg supports which are bolted to a bottom ring 5 and to atop spiderframe 6 to constitute acircular base structure. Secured upon the bottomring 5 and to the supporting legs 4 is a spider frame 7Y characterizedby having a center plate 8 into which is threaded a center shaft 9 thatex tends for a considerable distance above the base structure as shown.The top spiderl frame 6 includes a central plate member 10 `t roughwhich the center shaft 9 extends. y ecured upon the inner faces ofthesupporting legs 4, above the top 4spider frame 6 is a top ring 5carrying roller members 11 for the purpose of rotatably supporting ahood to be presently described.

Preferably and as shown, the top end of the center shaft 9 is madecone-shaped as at 12 and rotatable thereon is a stud member 13 havin a.cavity orbearing r ceptive of said cone-s apedend 12, the sad/ tudmember 13 bein rigidly carried by a two-part head 14 end of the sleeve15 is threaded a center plate 16S-carrying equi-spaced, radiallyextending T-shaped bars 17 designed to constitute a skeleton base forthe support of a compartmented rotary section. In the embodiment hereinshown, this rotary section is produced by supporting upon the T- shapedbars 17 a cylindrical casing or wall 18 which surrounds the center shaftand eX- tends a` distance thereabove. Bolted to and extending upwardlyfrom each of the radial bars 17 is a vertical'partition 19 whose innermarginal edge 19 is bentat an angle for se- -curement to the cylindricalmember 18, as

best shown in Fig. 3. These vertical par"- titions 19, by means of whichin association `with the cylindrical member 18 the rotary section isdivided into a plurality of milk can receiving compartments as 20,terminate at their upper ends in the planeV of the cylindrical member 18as shown in Fig. 2 gand the same are braced at their upper ends by thesector. bars 2l, best illustrated in Fig. 3. In this construction, eachof the compartments 20 is open at both its top and bottom ends and isalso open between the sector defined by the radially extendingpartitions 19. Each of thecompartments is provided at its bottom endwith a removable rack or grate 22 designed to rest4 upon the horizontalflanges or cross pieces 23 ofthe T-shaped bars 17. These racks serve asmeans for supporting in the compartments the milk cans while they arebeing washed by means of jets of steam,or of water, or of cleansingcylindrical sheathing 27, to the bottomend of which is secured acircular member' 28 of angular form in cross section so as' to oper#atively rest upon the rollers 11 wherebyV suit-` ably to support saidhood for ready rotation about the compartmented section. At the upperend of the cylindrical sheathing 27 is attached a re-inforcing ring28Kupon which is mounted a cone-shaped top 2 9 which terminates in acentral projecting portion 30 designed rotatably to receive the end of asuitable conduit 31 for the exit of the steam resulting from the washingoperations.

The hood 26 is provided with an opening or vdoorway 32 which ispreferably of the same size as each of the can receiving coinpartments20. Through this doorway the cans to' be washed are passed into thecompartments for the washing operations, and through this doorway alsothe cans are removed after -being washed. Moreover, this doorwayprovides an opening through which the racks 22 may be removed andapplied, it being remarked in this connection that the racks 22 may beof diderent types and designs. rlhis doorway, furthermore, providesready access to each of the compartments for the purpose of ascertainingwhether lthe washing operations are being carried on properly, it beingreadily understood from the description, taken in connectionwith theaccompanying drawings, that this hood is rotatable independently of therotation of the compartmented section. By preference, the hood isrotated manually, and to this end strips 38, adapted to be grasped bythe hand are positioned at intervals about the hood, the same beingconnected between the members 28 and 28. These vertically extendingstrips 33 also serve as braces for the hood structure. Owing to the factthat the doorway 32 is always open, itis desirable to prevent the steamfrom entering the compartments 2O from the cone-shaped top 29 when theattendant for the machine is engaged in placing cans in the compartmentsor removing them therefrom. To this end l provide a segmental plate 34which is supported by the hood in association with the doorway 32; thesaid plate being welded as at 35 or otherwise secured to thecone-shaped' top 29 immediately above the partitions 19, the saidsegmental plate being further supported by a flanged plate 36 whichconstitutes partof a supporting bracket 37 suitably attached to saidcone-shaped top 29. in this connection it will be observed that theflanged plate 3G is curved in agreement with the curvature of thecylindrical member 18 and that the'lange 38 of said plate serves as'sealing means for preventing the steam from entering the protected'compartment between the cylindrical member 18 l and the segmental plate34. By this arrangement, the steam is prevented from entering thecompartment wherewith the doorway 32 is in register* 39 represents atable which is located adjacent the rotary can washer for convenience inmoving the cans into and out of thel compartments,the said -table beingfurnished with a hinged leaf 40 adapted to -be positioned for the readytransfer of the cans from the table to the compartment or vice versa.

lVhile I have illustrated and described the preferred form ofconstruction for carrying my invention into ellect, this is capable ofvariation ,and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims. l

Having described my invention, what l. claim as new and desire to secureby Letters Patent is:
